Fax processing not successful - result (48) Disconnected after permitted retries
Hi, There are some inbound fax sessions which I got error code 48 (and in some cases 49). FreeSWITCH Version 1.0.head (git-54ddef0 2011-12-06 21-53-45 -0600) AS5350XM Voice / Fax ( T.38 ) Gateway I've noticed that this error appears in cases which there are complex documents (graphics or gray areas). appreciate all comments ! -- afshin

I've noticed that this error appears in cases which there are complex documents (graphics or gray areas). appreciate all comments ! If you have graphics, the pages generally take a lot longer to send. It is not uncommon for T.38 gateways to have stupidly short timeouts, which will cause a call to drop after a page has been in progress for just one minute, or one and a half minutes. Could that be your problem?

I also got this code, but in my scenario the called party didn't generating fax tone. I have tested FreeSWITCH with Images as well but never got such kind of code in that case. ----- Original Message ----- From: "Steve Underwood" <steveu@coppice.org> To: "FreeSWITCH Users Help" <freeswitch-users@lists.freeswitch.org> Sent: Wednesday, July 18, 2012 5:00:14 PM Subject: Re: [Freeswitch-users] Fax processing not successful - result (48) Disconnected after permitted retries On 07/18/2012 06:54 PM, afshin afzali wrote:

Hi Steve, I don't think that my problem relates straightly to the time that a fax takes to be received. In some cases I could get better result to decrease fax speed (normally causes longer time). Let me tell you my today case. There is a tabular document that I could receive from a Panasonic fax machine and the same time unable to receive that from a Canon machine. Although I'm receiving other (simpler than) documents from the Canon one ! I've tested various configurations on my 5350 device of modifying fax rate, ls_redundancy and hs_redundancy but could not managed to fix this.

A huge number of Canon machines have a broken V.29 modem, which produces such a poor signal you are lucky if other machines can decode it. The only real difference a complex image makes is the amount of data. This has only two effects: - Obviously it takes longer. - In ECM mode, if the image exceeds 64k it will be sent in 64k blocks, with error correction between each block. If your Cisco is running software more than a couple of years old, its T.38 engine may be horribly broken. It seems that had so much trouble with it, they tossed it out and put a complete replacement in there. The new one usually works well.

Steve, Thank you very very much :) I'll inform you of the result. Best, Afshin On Wed, Jul 18, 2012 at 5:31 PM, Steve Underwood <steveu@coppice.org> wrote:
